Hydraulic drive,all these components are quite heavy now but the bike applications would likely be made out of aluminum.
Fuel cell technology,likely a ways down the road as the present form would have to be miniturized quite a bit.
Tony,I like that two wheel drive idea but would that mean that the front tire would be as big as the rear now?..............ken.
I remember the story about the 2 wheel drive bike. Not sure if I'd want one, but it would be neat if they could get technology that far and sell'em. What about new saftey items, maybe an air bag you wore that deflates when your gonna get pavement friendly, (saw it in a mag).
Or more computerized things on the bikes.
that air bag idea is neat, you could have an emergency switch like on boats and jet skis, where if you fall off and yank the cord off, the engine dies, and your "airbag" suit deploys or some kind of protective measure happens...
